Another interesting note is that this also works in incognito mode, which could very well be utilized to fingerprint users across different sessions.

Except that there are a few problems with this view of technology. For a start: there is almost no evidence to say that screens are bad for us – even much-maligned social media. On the contrary, it looks as though, up to a certain limit, the use of social media correlates with wellbeing, and that some is better for us than none. And where there are negative correlations, such as that between social media and depression, or the amount of time we sit at a computer each day and our sense of our overall wellbeing, they are almost vanishingly weak. According to the best research, social media use correlates with depression to the same degree as eating potatoes does – which is to say, not very much at all.
